Your ship has loaded 20,000 barrels of crude oil, departing Valdez, Alaska for San Francisco. When loaded the cargo temperature was 96°F. API was 15°. The volume correction factor (VCF) is .0004. If the cargo temperature is expected to be 56°F at the discharge port, how many gallons will be offloaded?

Correct Answer: Option D — 826,560

Temperature drops from $96^\circ\text{F}$ to $56^\circ\text{F}$ ($40^\circ\text{F}$ drop). Contraction is $20,000 \times 0.0004 \times 40 = 320$ barrels, leaving $19,680$ barrels. Converting to gallons ($19,680 \times 42$) yields $826,560$ gallons, accounting for significant thermal reduction in cargo volume.
